I am still not clear on what the real question is. For example, if the question is "Have I a large enough sample to accurately estimate the mean, and standard deviation of the population?" you might split the data set, and then calculate t, and f for each half, and compare them to the total sample's parameters. If the results indicated that the sub-samples were basically the same, then problem solved.

ETA: There is a statistic to test if one has sampled the SD of a population that is an application of Chebsyev's Theorem, but I am having a caffeine deficit disorder.
